Are smooth and cardiac muscle tissues under voluntary control?

Smooth and cardiac muscle tissues are classified as involuntary muscle types, meaning they operate without conscious control. Smooth muscle is located in various structures such as the walls of blood vessels and the digestive tract, where its contractions are regulated by the autonomic nervous system and various hormonal signals, allowing it to respond automatically to the body's needs.

Cardiac muscle, found exclusively in the heart, also functions involuntarily. It contracts rhythmically and continuously without requiring signals from the brain, although it is influenced by the autonomic nervous system to modulate the heart rate based on the body's demands, such as during exercise or stress.

In contrast, skeletal muscle is the type of muscle that is under voluntary control, allowing for conscious movement. The distinction between voluntary and involuntary muscle types is crucial for understanding how different muscles contribute to bodily function.
